“Pax Vobiscum” is a 1890 work by Henry Drummond containing a selection of some of his best sermons on a range of topics from Christian philosophy to the attainment of happiness. Contents include: “Introductory”, “Effects Require Causes”, “What Yokes are For”, and “How Fruits Grow”. Rev Prof Henry Drummond (1851–1897) was a Scottish biologist, evangelist, lecturer, and writer. He had an incredible religious influence on his own generation, and his sermon ‘The Greatest Thing in the World’ is still popular within Christian circles. Other notable works by this author include: “Natural Law in the Spiritual World” (1883), “Tropical Africa” (1888), and “The Greatest Thing in the World: an Address” (1890). This vintage book will appeal to those with an interest in Christianity and is not to be missed by fans and collectors of Drummond’s influential work. Many vintage books such as this are becoming increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with an essay on religion by James Young Simpson.
